JOSEPH SIIVIEON BERARD, OF FALL RIVER, MASSACHUSETTS.

TENSION-BEGULATING DEVICE FOR SPINDLE-BANDS.

To all whom it may-concern:

Be it known that I, JOSEPH SIMnoN BE- nann, a citizen of the UnitedStates of America, and a resident of Fall River, in the county ofBristol and State of Massachusetts, have invented new and usefulImprovements in Tension-Regulating Devices for Spi11dleBands, of whichthe following is a specification.

hiy invention relates to an improvement in spindle driving devices, andits object is to provide means for driving the spindles or revolvingrings without the necessity of using the ordinary cylinder.

The invention consists of many novel features of construction andcombinations of parts to be hereinafter described and pointed out in theclaims.

In the accompanying drawings: Figure 1 is a side view of a frame showingmy invention applied thereto; Fig. 2 is an end view with one end of theframe removed; Fig. 3 is a detailed sectional view; Fig. 4 is an endview of the tightener; and Fig. 5 is a side view.

A represents a frame and 2 is a driving shaft mounted on the frame. Agrooved wheel 3 is journaled on the shaft 2 and is driven by a fly wheel4; on the shaft. A shaft 6, extending transversely of the machine, isprovided with grooved wheels 5 and 5 on both sides of the machine overwhich a rope 7 is adapted to pass which travels over the grooved wheel3. The rope 7 extends to the far end of the machine, passing overgrooved wheels 10 mounted on pins 11. The rope passes around the wheels10 and returning along the other side of the machine and over the wheel5 to the grooved wheel 3. Mounted on the rail 8 are spindles 9, andmounted on the spindles are whirls or rings 12, which are adapted to beengaged by the rope 7 for rotating them. Shafts 13 are journaled in theframe and mounted on the shafts are tighteners 14. The tighteners areconnected to the shaft by arms 15 and fastened to the shafts 13 arelevers 16 by thumb screws 17, the levers being received in the forkedends of the arms 15. Springs 18 connect the lower ends of the leverswith the tighteners 14. Mounted on the tighteners 1 1 are whirls 19,which Specification of Letters Patent.

are adapted to be held against the rope 7, causing an engagement of thewhirls or rings 12 on the spindles with the rope whereby the whirls orrings 12 are rotated. The springs 18 cause the whirls 19 to be heldagainst the rope causing suflicient friction to drive the whirls 12. Alug or projection 20 is formed on the tighteners, which is adapted to beengaged by the lever 16 when it is desired to release the tightenersfrom the rope and stop the whirls 12. An oil duct 21 is formed in thelug or projection 20 for conveying oil to the different parts of thebolster (not shown) inside of the tightener. A handle 22 is connected tothe shaft 13, whereby the lever 16 is caused by the rotation of theshaft to engage the lug or projection 20 causing the tighteners to betipped rearwardly and thereby loosening the rope and preventing therotation of the whirls 12.

It is evident that more or less slight changes might be resorted to inthe form and arrangement of the several parts described withoutdeparting from the spirit and scope of my invention, and hence I do notwish to be limited to the exact construction herein set forth, but:

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a spindle driving device, the combination with a frame, ofspindles, a driving band or rope, shafts journaled in the frame,tighteners mounted on the shafts and adapted to engage the band, wherebythe band is caused to engage the spindles for revolving them and meanson the shafts adapted to engage the tighteners for moving themsimultaneously out of contact with the driving band.

2. In a spindle driving device, the combination with a frame, ofspindles, whirls mounted on the spindles, a drive rope adapted to engagethe whirls, shafts journaled in the frame, tighteners mounted on theshafts and adapted to engage the rope causing the spindles to berotated, levers on the shafts adapted to engage the tighteners formoving them simultaneously out of contact with the rope.

3. In a spindle driving device, the combination with a frame, ofspindles, whirls mounted on the spindles, a drive rope adaptto engagethe lugs for moving the tighteners ed to engage the whirls, shaftsjournaled in simultaneously out of contact With the rope.
